- 3. A block with mass m is connected to two springs having constant forces k₁-2k and k=k. The system is initially in equilibrium on a horizontal, frictionless surface. Then, the block is pushed d distance to the right from rest, a. Draw the free body-diagram for the system and calculate the work done by the acting all forces. b. After the block release what will be the maximum speed of the block and what will be the maximum compression of spring 1? k₁ Spring 1 Spring 2A spring with a force constant of 300 N/m is attached to and compressed by a 4 kg mass to a compression of 1.5 m. The mass is released from rest. The surface is frictionless. How much time does it take the mass to return to the equilibrium position the first time after release? What is the velocity of the mass when it returns to the equilibrium position the first time after release? Include sign.6. While demonstrating springs, i pushed on the top of my ball point pen with a maximum force of 0.901 newtons which compressed the little springs in the pen by 0.0132. then i help the pen top next to a gold ball and released the spring. it pushed the ball which rolled across the table. the mass of the ball was 0.0379 kg. calculate the speed of the golf ball after the pen pushed it
- A wooden box of mass 6.0 kg slides on a frictionless tabletop with a speed of 3.0 m/s. It is brought to rest by a compressing spring. The spring content is 1250 N/m. a. Calculate the maximum distance the spring is compressed. b. Determine the speed and acceleration of the block who the spring is compressed a distance of 14 cm.A 3.59 kg ball is held at rest exactly 3.7 meters in the air. Assume their is no spring in this problem. A. How much gravitational potential energy does the ball currently have? Joules B. How much kinetic energy does the ball currently have? Joules C. How much total mechanical energy does the ball have currently? Joules The ball is than allowed to fall to the ground. As the ball falls It gravitational potential energy gets converted into Kinetic Energy. The moment before hits the ground all of its energy is in the form of kinetic energy. D. How much G.P.E does the ball have the moment before it hits the ground? Joules E. How much kinetic energy does the ball have the moment before it hits the ground? Joules F. what is the ball's speed the instant before it hits the ground? m/sUse g = 10m/s/s
